Signora Jewels builds this oval lab grown diamond engagement ring around two close rows of small round stones. The inner halo tightens against the oval while the outer row extends its outline, so the center reads broader without adding width to the plain lower shank.
The four-prong basket leaves the long sides of the oval open to light. At the reference 2.00 ct size, the 10.22 × 7.16 mm center rises above 120 accents, while the smooth back half keeps the ring comfortable between the fingers.

The outer halo follows the oval rather than forming a round border. That keeps the elongated outline clear from the first glance and gives the ring its layered face-up spread.
Diamond & Ring Details
The reference ring contains one 2.00 ct oval center and 120 round accents totaling approx. 0.50 ct. The center is secured by four prongs, and both halos use individual prong settings. Selecting another center weight scales the basket and halo proportions while preserving the same double-halo layout. Read our engagement ring guide before choosing the center size.
About Lab Grown Diamonds
An oval brilliant carries round-style sparkle through an elongated outline. Its length draws the eye along the finger, while the double halo adds a second band of reflected light around the center.
Lab grown diamonds have the same crystal structure, hardness and optical properties as mined diamonds. Learn how their grading and origin work in our lab grown diamond guide.
Metal, Care & Fit
Choose sterling silver, 9K, 14K or 18K gold in yellow, white or rose, or platinum. The reference size is US 8. Clean beneath both halos with warm water, mild soap and a soft brush, then rinse and dry thoroughly. Remove the ring before swimming, heavy lifting or applying lotion.
FAQ
Can I change the oval center diamond size?
Yes. The oval center is available from 1.00 to 4.50 ct, and the basket and halo proportions scale with the selected weight.
What is the total diamond weight in the reference design?
The reference design is approx. 2.50 ct total, made from a 2.00 ct oval center and approx. 0.50 ct of round halo diamonds.
How many accent diamonds are in the double halo?
The double halo contains 120 round accent diamonds: 16 stones at 1.00 mm and 104 stones at 0.90 mm.
Does the double halo make the center look larger?
Yes. Two closely fitted rows extend the oval outline beyond its girdle, increasing its visible face-up spread.
What is the difference between a single halo and this double halo?
A double halo adds a second complete row of diamonds, giving this ring a broader outline and denser light return than a single-halo setting.
What is the difference between 9K and 18K gold?
18K gold contains more pure gold and has a richer color, while 9K gold is harder and more resistant to everyday surface wear.
Are lab grown diamonds real diamonds?
Yes. A lab grown diamond has the same hardness, chemistry and optical properties as a mined diamond, and every Signora Jewels center ships with an IGI report.
Can this ring be resized?
Yes. The plain lower shank allows most gold and platinum versions to be resized by a qualified jeweler.
